In this letter, constructions of sequences with perfect odd autocorrelation and sequence sets zero correlation zone (ZOCZ) over the 8-QAM+ constellation are presented. Based on ternary sequences, ZOCZ constructed by using shift vectors mappings. These can be used in communication systems to achieve high transmission data rate (TDR) low interference.
